At the meeting of the League of Countries, the representative from Kapecapek announces his government's decision to close its borders to the outside world. An official proposes that if Kapecapek's racecar driver, named Kabala, beats Speed Racer, then its borders can remain closed. At the racetrack, Speed receives an invitation to the Fire Festival Race. Speed finds this peculiar because Kapecapek doesn't have a racetrack and Kabala has been missing for a long time. Nevertheless, Speed and company arrive in Kapecapek. They spot Racer X, who was also invited. That night Chief Zuma lets it be known that "the winner of the race will be bridegroom" to his granddaughter, Princess Sibana. He points out Speed as the probably winner. But when a jealous Trixie makes it clear that Speed is taken, another driver, Mr. Kadar, steps forward with his offer of matrimony. Later, Mr. Kadar captures the Princess and demands to know where the country's treasure is hidden. Speed comes to her rescue.
